Linux Kernel 7.2 Merges AF_ALG Cryptographic Driver Deprecation

The cryptographic subsystem updates for the upcoming Linux 7.2 kernel have been merged, including the deprecation of the AF_ALG driver. This decision removes what is described as "useless & insecure crypto driver code." The AF_ALG (Userspace Cryptographic API) is a kernel interface that allows userspace programs to access cryptographic algorithms. Its deprecation suggests that alternative, more secure, or efficient methods are now preferred within the Linux kernel. This move is part of the ongoing effort to maintain and improve the security and performance of the Linux operating system. Developers contributing to the kernel have approved this change. The removal of potentially vulnerable code enhances the overall security posture of the Linux kernel. Users relying on AF_ALG may need to transition to newer cryptographic interfaces.

This technical update pertains to the Linux kernel, detailing the removal of outdated and insecure cryptographic code, which contributes to the overall security and stability of the operating system.
